WATERPROOF CATTLE CARD.

Application filed September -25, 1924. Serial No. 739,839.

This invention relates to the manufacture of cattle cards, and incidentally to the preparation of the material from which such cards are made, and has for its ultimate object the production of an inexpensivercard which willbe sufficiently substantial and durable to perform its intended function in a satisfactory way and which is not injuriously affected by its use upon wet animals.

The foregoing and other objects of the invention will best be understood from'the following description of the manufacture of a cattle card in accordance therewith, as illustrated in the accompanying drawings. It will be understood, however, that the particular construction shown and the particular operations and materials described have been chosen for illustrative purposes merely, and that the invention, asdefined by the claims hereunto appended, may be otherwise embodied and practiced without departure from the spirit and scope thereof.

In said drawings: i

Fig. lis a longitudinal section, taken substantially on the line 11, Fig. 2, of a complete cattle card having a face embodying and produced in accordance with the invention.

Fig. 2 is a partial bottom plan view so thereof.

Figs. 3 and 4- are enlarged detail sections of portions of the card face, illustrating the same before and after the final preparation, respectively. a

In Figs. 1 and 2 is shown a cattle card comprising a back or body 10 of wood or other suitable material provided with a suitable handle 11 and having secured to the face thereof, as by tacks 12 or otherwise, the card proper to which the present invention relates. 13 of fibre stock having inserted therein metal teeth 14. The fibre sheet 13 is initially prepared by punching therein holes 15 (Fig.3) in such a manner as to form adjacent said holes struck up lips 16 which serve to reinforce and brace the teeth 14. Said teeth as herein'shown, comprise wire staples having shanks which are inserted through the holes 15 from the back of the sheet and which are formed with angularly offset ends, the resulting structure being substantially as more fully shown and described in Patent No. 1,571,937, issued Feb. 9, 1926.

After the insertion of the teeth 14 in the Said card proper comprises a sheet fibre sheet 13, the whole is, in accordance with the present invention, immersed and allowed to soak for from five to. ten minutes n a waterproof varnish, preferably consistmg of a substantially saturated solution of rosin in a light liquid hydrocarbon, such as benzine or gasoline, after which the sheet'is withdrawn and allowed or more. 7

' The immersion of the fibre sheet in the rosin solution'causes the latter to forma to dry foran hour coating 17 on the surface of the stock and also to penetrate and impregnate the sub 9 stance of the stock to greater; or less ex-; tent depending upon therelative density of the stock and solution. The varnish coating also fills the interstices about the teeth 14 and between the same and the walls of the holes 15, also impregnating the stock about the latter to a greater or less extent, as indicated in F igy4. Moreover it has been found in'practicethat the rosin in the solution impregnates the fibre sheet and hardens or stifi'ens it as well as waterproofing it. i I

The use of fibre stock with inserted Wire teeth permits the manufacture of cards at a very low cost, while the coatingof waterproof varnish enables the stock, notwithstanding its cheapness, to withstand moisturev which would otherwisetend to soften the same and result in, the ultimate destruction of the'card. It has been found by experiment that a card thus prepared will stand immersion in water for five or six hours without absorption, which is, of course, a much more severe test than s encountered in" actual use. It is also found that the filling of rosin or varnish about the teeth in the openings in the card acts to support said teeth firmly and results in a construction which is much more rigid anddurable in this respect than any similar card as heretofore made. It will be seenthat the mater als employed are all relatively cheap, and

that the process involved is also simple and v inexpensive, so that the cards can be produced at very low cost while being capable of giving service which is satisfactory in every way. a

Having thus described my invention, ,1 claim:

1. A waterproof cattle card comprising a sheet of fibre stock having holes therein, metal teeth in said holes, and a coating of Waterproof varnish containing rosin covering the surfaces of said sheet and filling the interstices about said teeth, said rosin impregnating the fibre sheet to harden the 5 same.

2. A Waterproof cattle card comprising a sheet of fibrous stock having holes therein,

,tion impregnating the fibre sheet to stifien the same,

In testimony whereof, I affix my signature WHITNEY M. FRYE. w
